MONOLITHIC POWER SYSTEMS INC Q3 FY2026 earnings call

• Revenue Milestone: Achieved over $1 billion in quarterly revenue for the first time, reaching $1.2 billion in Q3 2026.
• Capacity Expansion: Current annual revenue support capacity has surpassed $6 billion. The company targets $8 billion in capacity by H2 2027, aiming for $10 billion long-term to support rapid expansion.
• Enterprise Data Growth: Strong demand persists across existing customers with expectations to continue into 2027. Utilization of in-house AI design tools expanded the customer base in traditional areas and secured new wins in desktop AI designs.
• Automotive Developments: Received first orders for 48-volt power solutions. Design wins for 48-volt and zonal architectures are expected to drive growth in 2027.
• Robotics & Industrial: Started ramping robotic solutions featuring sensor and motor control products across multiple geographies.
• Product Portfolio Expansion: Increased Total Addressable Market (SAM) via high-speed memory products. Secured first large data converter design win, expected to ramp next year. Began sampling GaN-based solutions for 800-volt data center architectures, complementing existing silicon carbide (SiC) designs.
• Capital Returns: Repurchased over $450 million of stock during Q3.

The transcript does not provide a detailed breakdown of financial performance by specific product segment (e.g., Automotive, Data Center, Industrial) in terms of absolute revenue figures or percentage contribution. The company reports consolidated third-quarter revenue of $1.2 billion, representing 22% sequential growth and 63% year-over-year growth. Management highlights strong demand across Enterprise Data, Communications, and growing contributions from Automotive and Robotics, but specific segment-level P&L data is not disclosed.

• Enterprise Data Floor Raised: Management raised the floor for Enterprise Data year-over-year growth from 130% to 150%, citing intact structural drivers including customer diversification, module adoption, and content gains.
• Communications Outlook: Positioned Communications as the second-fastest-growing end market, driven by optical modules transitioning to 1.6T (volume and content play) and the switch business ramp.
• Operating Leverage: At current top-line growth rates (50-60%), operating expenses are falling below model ranges due to efficiency rather than reduced spending, leading to material operating leverage.
• Gross Margin Stability: Gross margins are maintained within the 55%-60% sweet spot with slow, methodical expansion. Management emphasizes consistency and avoiding margin volatility.
• Long-Term Visibility: No specific quantitative guidance provided for 2027 full-year results, but management expresses high confidence in sustained accelerated growth driven by diversified end markets and new technology ramps.

• Technology Reliability (GaN): GaN is a new technology for the industry; management aims for <1 ppm failure rates but notes it requires significant validation (e.g., 50 million units) before being deemed as reliable as established SiC solutions.
• Notebook PC Constraints: Short-term weakness in Notebook segments due to downstream memory constraints, though long-term outlook remains positive due to edge AI applications.
• Inventory Management: Channel inventory is kept lean (5-8 weeks); while currently not limiting sales, any disruption in this balance could impact short-term visibility.
• Cost Absorption: Rising foundry wafer costs are partially absorbed by MPS rather than fully passed through to customers to maintain relationships, which may pressure gross margins if costs rise significantly.

Q: Analyst asked about the sustainability of accelerated growth and when $10B capacity will be achieved. / A: CEO stated there are no signs of slowdown in this explosive growth period. CFO added that growth is broadening beyond enterprise data into auto and robotics, giving confidence in continued acceleration. Capacity roadmap targets $8B by H2 2027 and $10B thereafter.

Q: Analyst inquired about the positioning, process type, and revenue timing for 800V GaN solutions. / A: CEO explained NPS uses its own developed vertical GaN process, offering customers a choice between GaN and SiC based on reliability needs. CFO noted that while design work is ahead, revenue realization is likely late 2027 or 2028, consistent with previous timelines for 800V architecture ramps.

Q: Analyst asked for segment splits in Storage/Compute (SSD/HDD vs. DDR5 vs. PC) and OpEx scaling rules. / A: CFO identified DDR5 PMICs as the primary growth driver in storage, while notebook PCs face short-term headwinds from memory constraints but remain bullish long-term. Regarding OpEx, CFO confirmed that at high growth rates, spending falls below model projections due to R&D efficiency, creating operating leverage without changing the underlying cost structure.

Q: Analyst requested updated growth floors for Enterprise Data and details on Comms breakout. / A: CFO raised the Enterprise Data YoY growth floor to 150%, supported by ASIC customer growth and module adoption. For Comms, CFO attributed Q3 strength to the combination of optical modules and the newly added switch business, expecting both to drive growth into 2027.

Q: Analyst asked about the diversity of Enterprise Data revenue (GPU vs. ASIC, Module vs. Discrete) and the potential of high-speed data converters. / A: CEO highlighted rapid growth among ASIC customers using modules. CFO emphasized that AI tools allow them to address a long tail of small customers who may become large later. Regarding data converters, management declined to predict specific revenue contributions, noting they serve all segments aggressively and cannot predict which will dominate years in advance.
